Three main parameters should be tracked closely:
1. pH
2. Free chlorine
3. Alkalinity
T.D.S. (Total Dissolved Solids) and calcium hardness should be
checked after the first three are in the correct range. Test strips and
test kits come with instructions on how to diagnose readings to
determine whether the chemicals are in the right range. Table 2-1
shows how to dispense chemicals and how often to do it.
In the beginning, it is a good idea to test your water daily to learn how the
water changes with the addition of chemicals. By keeping a log, you will be
able to keep better track of your water condition.
When adding water to your spa for the first time or changing the water, you
should superchlorinate the water by doubling (1 tbsp. Per 100 gallons) the
regular dose of chlorine. It is a good idea to wait for 8 hours before entering
your spa after superchlorinating the water.
Remember that keeping your spa water healthy keeps you, your family, and
your guests healthy too. Most service calls for spa repairs are related to prob-
lems caused by not maintaining balanced spa water.
